ABSTRACT:
A DIP or surface mount type switch (10) contains a built-in electronic system for direct interfacing to an electronic circuit. The DIP switch and the built-in electronic system consisting of bias resistors (22), active buffers (14), and decoding circuitry (18), are combined as a single package. These components will be mounted and interconnected to a substrate PCB (26), or chip carrier package (31), or as an integral unit within the switch housing (12). This DIP switch also includes socket pins or mounting leads (30) to connect the assembly to a system circuit board.
